The tech titan has sent out a minimalist invitation which simply reads ‘It’s almost here’ and features a bold ’12’ emblazoned in the centre of the page, above a shadowy ‘5’.

A larger, thinner iPhone 5 is expected to be unveiled at the event, in Apple’s first big occasion since the death of its long-time leader Steve Jobs .While last year’s iPhone 4S saw only small cosmetic changes made from the previous model, the iPhone 5 is expected to be something of a departure.Apple is a famously secretive organisation when it comes to new products, although leaked photographs thought to be of components from the device point to a larger 4.2 inch screen and a thinner body.

The current 30-pin connector at the base of the iPhone is also thought to have been replaced with a much smaller one.

Furthermore, the iPhone 5 is also anticipated to offer 4G high-speed wireless broadband connectivity in the US in order to compete with the increasing number of Android devices that carry the service.
